Heterologous production, characterization and dye decolorization ability of a novel thermostable laccase isoenzyme from Trametes trogii BAFC 463

Laccases are multicopper polyphenol oxidases that are able to catalyze the oxidation of a wide range of phenolic compounds with the simultaneous reduction of O2 to H2O. Despite their promising industrial uses, feasible incorporation of laccases in harsh processes requires the bioprospecting and/or e...
